Duplex structure facilitated by aqua ligand in a copper(II) coordination polymer

The structural aspects and magnetic properties of a novel five-coordinated copper(II) coordination polymer derived from a carboxylate tethered naphthalimide ligand, namely 5-(1,3-dioxo-1H, 3H-benzo[de]isoquinolin-2-yl)-isophthalic acid are presented. The coordination polymer having monodentate carboxylate groups connecting the copper ions to form a spiral duplex structure shows anti-ferromagnetic property.

The role of coordinated water molecules in a novel five-coordinated copper(II) coordination polymer having spiral duplex structure showing anti-ferromagnetic property is discussed.Figure optionsDownload as PowerPoint slideHighlights
► A naphthalimide bearing coordination polymer of copper(II) having spiral duplex structure is presented.
► The orientations of the aqua-ligands in the chains are responsible for the formation of duplex structure.
► The penta-coordinated coordination polymer is weakly antiferromagnetic.
